Abstract
Image artefacts appearing when a checkerboard pattern spatial compression is applied to luminance-chrominance color space images having subsampled chroma data, such as YCbCr, is avoided by using a different checkerboard pattern for the luminance pixels than the pattern used for the chrominance pixels.
Description
Technical field
The spatial image that the present invention relates to delete pixel according to comprising of checkerboard pattern compresses.
Background technology
Image transmits desired memory data output to image compression and bandwidth is important for reducing.
Be known that and in video compression, use quincunx (quincunx) or tessellate (checkerboard) pixel decimation (decimation) pattern.In the US patent application open file 2003/0223499 of general appointment,, right with the stereo-picture of compression three-dimensional video-frequency by removing the pixel and the checkerboard pattern of horizontal packed pixel then in the checkerboard pattern (pattern).The image of two level compressions is placed in the single standard picture frame by side-by-side subsequently, thereby (for example: MPEG2) is applicable to traditional image compression.Subsequently the standard drawing picture frame that decompresses is expanded to the pixel that checkerboard pattern and space ground interpolation (interpolate) are lost.
Summary of the invention
It has been found that, be different from the pattern that is used for colourity (chrominance) pixel if be used for the checkerboard pattern of luminance pixel, then can avoid when the checkerboard pattern space compression being applied to brightness-colourity color space image, YCbCr for example, the image artifacts that is occurred (image artefact).Such image can utilize the full spatial resolution of the pixel that is used for luminance channel to encode, simultaneously for odd pixel to chroma pixel, just blue Cb and red Cr encode.For example, when with respect to brightness with resolution Smalt and red color data minus half, be referred to as 4:2:2 coding.Known other coding techniques that can further reduce chroma data, for example 4:2:0 and 4:1:1.Expression formula 4:4:4 is generally used for referring to brightness and the equal resolution of chroma data.It has been found that, when in luminance channel, keeping full resolution, and when in colour or chrominance channel, using half-resolution, any significant loss that human eye can not the perception colour resolution.Show prepare image completely in order to produce, the even number chrominance section of the pixel of YCbCr source images is repeated simply or is carried out interpolation by adjacent odd pixel by odd pixel before.When luminance pixel was used identical checkerboard pattern, the chroma pixel that is kept by pattern was pixel interpolation or that repeat sometimes, is not original source image pixels.When being used to regenerate complete image, the space compression checkerboard pattern of pixel can produce visual pseudo-shadow.The different pattern that is used for chroma pixel is the pattern of original pixels (for example, odd pixel is not the pixel of interpolation or repetition), preferably still is checkerboard pattern.

Embodiment
In the following description, introduce embodiments of the present invention, wherein in execution mode, use color space form YCbCr with 4:2:2 compression.In this case, each original source pixel has the brightness (luminance) or the brightness value (brightness) of its appointment in the source, yet has ignored even number Cb and Cr pixel.When such image transitions was the RGB shows signal, even number Cb and Cr pixel repeated the odd number value of front or by other odd number Cb and Cr pixel interpolating, and even number R, G and B value are used for indivedual brightness values of even pixel.When producing YCbCr demonstration output, by simply repeating or passing through spatial interpolation, even number Cb and the Cr pixel missed are carried out interpolation once more from the source.Cognoscible is that the present invention can be applied to different colourity sub sampling forms.
In Fig. 2 B, the source chrominance section (component) of the YCbCr image of Fig. 2 A has been reverted to and had even number and odd number chroma pixel.In order to use the checkerboard pattern that is used for luminance pixel among Figure 1B that this image is encoded, keep the pixel in the checkerboard pattern, and extract (decimate) remaining pixel.Shown in Fig. 2 C, odd-numbered line comprises original Cb and Cr pixel, and even number line only comprises the Cb and the Cr pixel (pixel of interpolation underscore value representation) of interpolation.In order to keep the 4:2:2 form, image encoded is included as the luminance pixel of chroma pixel twice, and therefore extracts half pixel to be provided for encoding in the chroma pixel that is kept, shown in Fig. 2 D.These chroma pixels can be rearranged for and be used in independent single vision (monoscopic) video data frame chrominance channel storing stereoscopic right eye side by side (side-by-side) or the frame format that up and down be connected right with left-eye image.
When this coded image of Fig. 2 D recovers (promptly, during decoding) to pixel (Fig. 2 F) that original 4:4:4 checkerboard pattern (Fig. 2 E) and interpolation are lost, the chroma pixel of even number line comprises the odd pixel of the interpolated pixel (representing with double underline) according to interpolated pixel, and according to the even pixel of the original pixels of interpolation.The pixel of representing with double underline is followed according to neighbor and is carried out interpolation, and wherein neighbor self has the interpolate value from original pixels.Being original odd-numbered line and even number chroma pixel with the odd number chroma pixel compares from the odd-numbered line of original pixels interpolation, has significant difference for chroma pixel between odd and even number is capable.Under most of situation, this difference causes tangible image artifacts.
In some cases, desired output also can be 4:2:2, and Fig. 2 G shows the image block into the chroma pixel of 4:2:2.Shadows pixels is the pixel that has mistake with respect to the original pixels of Fig. 2 A.
In Fig. 3 A, the checkerboard pattern of use source chroma pixel extracts the image block of Fig. 2 A.If this operation is to carry out, then in pattern, use source pixel on the source YCbCr image that returning to shown in Fig. 2 B is had even number and odd number Cb and Cr pixel.Be understandable that, there is no need the chroma pixel that interpolation is lost in this embodiment.In order to use checkerboard pattern that this image is encoded, keep the luminance pixel in first checkerboard pattern (with among Figure 1B identical) and extract remaining pixel.Use different checkerboard patterns for chroma pixel.The colourity checkerboard pattern does not comprise the chroma pixel of interpolation based on original chroma pixel.
As shown in Figure 3A, odd-numbered line comprise from the original Cb and the Cr pixel of the same pixel position of the luminance pixel of odd-numbered line, even number line comprises the original chroma pixel adjacent with the luminance pixel of even number line simultaneously.Because the colourity checkerboard pattern has been in half of resolution of brightness checkerboard pattern, need further not extract the pixel that is kept in order to satisfy the 4:2:2 form.
These chroma pixels of Fig. 3 A can be rearranged for be used for independent single vision video data frame chrominance channel storing stereoscopic vision right eye and left-eye image right side by side or the frame format that is connected up and down.When these coded images being recovered or be decoded as original checkerboard pattern and the pixel of losing carried out interpolation, chroma pixel is original pixels or carries out interpolation by original pixels.In the decoded picture of this execution mode, there is not tangible difference between even number and the odd-numbered line in essence.
Because each pixel has the original pixels of two direct neighbors in vertical direction and have two original pixels on 2 horizontal directions that list among Fig. 3 A, to carry out the situation of interpolation more efficient than the situation of Fig. 2 D to losing pixel among Fig. 3 A.Under the situation of Fig. 3 B, can also reduce the amount of calculation of recovering the 4:2:2 image than generating Fig. 2 G.
In Fig. 3 B, the chromatic diagram picture of recovery has in the wrong sub-sampled images piece in the original picture block with respect to Fig. 2 A and has 3 pixels.This compares with Fig. 2 G with 9 erroneous pixel.Certainly each the wrong pixel in the sub-sampled images piece can pass to its mistake adjacent interpolated pixel in the full resolution colourity image block.
Scrutable is when the image of Fig. 3 B returns to 4:4:4 resolution, can accurately calculate each pixel of losing from Fig. 3 A from the source pixel of direct neighbor.Since presented enough adjacent original pixels for accurate interpolation, therefore need be by calculating pixel in the adjacent pixel values, and wherein adjacent pixel values self also is interpolated.
In execution mode shown in Figure 4, be used for that the device of colourity sub sampling coding video data is had left eye and eye image buffer and two pixel decimation devices (decimator).Withdrawal device is configured to keep the regular checkerboard pattern of the source luminance pixel of full resolution, and another withdrawal device is configured to keep the checkerboard pattern less than the horizontal extension of the full resolution of source chroma pixel, and do not comprise keep interpolated pixel in the pixel.Withdrawal device is configured to read and alternate treatment extraction processing between two buffers from two buffers.Perhaps, can be provided in right eye and the left eye path the independently withdrawal device of each.Frame merges circuit and arranges abstract image to be used for output, to compress and storage or transmission especially for MPEG with the form that merges side by side.This merging comprises arranges pixel to satisfy the resolution of output frame.Be understandable that, the arrangement of other merging frame can be provided.Will also be appreciated that " left eye " source and " right eye " source can be the incoherent sources that will store together or transmit, or the frame of single source sequence or graded area.In illustrated embodiment, image source is the 4:2:2 form, and other form also can simultaneously.
In execution mode shown in Figure 5, decoder has two interpolaters (interpolator), one is used for luminance pixel, wherein lose the additional checkerboard pattern of pixel from the checkerboard pattern interpolation of pixel, and second be used for chroma pixel, wherein from the checkerboard pattern interpolation pixels of losing of the horizontal extension of original source chroma pixel more.Interpolater calculates the pixel value of interpolation to provide the 4:2:2 resolution shown in Fig. 3 B.In other embodiments, interpolater can at first arranged pixel before the pixel value that calculating is lost in full resolution grid or matrix.As withdrawal device, interpolater can provide copy in right side and the left pixel passage each, and perhaps they can replace operation on right side and left-side images.The output of interpolater can be stored in the buffer before further handling or exporting.Be understandable that the output of decoder is the 4:2:2 form, carried out that before showing the chroma video data are converted to full resolution.
The execution mode of Fig. 4 and Fig. 5 can use on traditional F PGA equipment spendable circuit to realize.Perhaps, desired processing can be carried out in CPU, and just computer server or work station use software with carries out image processing.
